Terrestrial planets are substantially different from the giant planets, which might not have solid surfaces and are composed mostly of some combination of hydrogen, helium, and water existing in various physical states. Terrestrial planets have a compact, rocky surfaces, and Venus, Earth, and Mars each also has an atmosphere. Their size, radius ...
Saturn – sixth planet from the Sun and the second-largest in the Solar System, after Jupiter. It is a gas giant with an average radius about nine times that of Earth . [ 1 ] [ 2 ] Although only one-eighth the average density of Earth, with its larger volume Saturn is just over 95 times more massive.
Saturn is known as "Shani" and judges everyone based on the good and bad deeds performed in life. [139] [141] Ancient Chinese and Japanese culture designated the planet Saturn as the "earth star" (土星). This was based on Five Elements which were traditionally used to classify natural elements.

A terrestrial planet, tellurian planet, telluric planet, or rocky planet, is a planet that is composed primarily of silicate, rocks or metals. Within the Solar System , the terrestrial planets accepted by the IAU are the inner planets closest to the Sun : Mercury , Venus , Earth and Mars .
The magnetosphere of Saturn is the cavity created in the flow of the solar wind by the planet's internally generated magnetic field. Discovered in 1979 by the Pioneer 11 spacecraft, Saturn's magnetosphere is the second largest of any planet in the Solar System after Jupiter .
At first, Skathi was given the temporary name "S/2000 S 8": the first "S" denotes that Skathi is a satellite (as opposed to, say, a planetary ring), "2000" specifies that it was discovered in the year 2000, the second "S" is assigned because it orbits the planet Saturn, and the number 8 means that it was the eighth such object discovered in ...
This is a list of named geological features on Saturn's moon Titan. Official names for these features have only been announced since the 2000s, as Titan's surface was virtually unknown before the arrival of the Cassini–Huygens probe. [1] [2] Some features were known by informal nicknames beforehand; these names are noted where appropriate ...
Cassini Regio / k ə ˈ s iː n i ˈ r iː dʒ i oʊ / (adjective Cassinian / k ə ˈ s ɪ n i ən /) [1] is the enigmatic dark area that covers the leading half of Saturn's moon Iapetus. It is named after Giovanni Cassini , the discoverer of Iapetus; ' Regio ' is a term used in planetary geology for a large area that is strongly differentiated ...
